Vacuum tempering series equipment includes five categories: 7.1 horizontal double chamber oil cooled type, 7.2 vertical double chamber oil cooled type, 7.3 horizontal double chamber high-pressure air cooled type, 7.4 horizontal single chamber air cooled type, 7.5 vertical single chamber air cooled type;
Main purposes of vacuum tempering furnace:
It is mainly equipment for processing nonferrous metals. After the nonferrous metals are quenched, cracks and other problems may occur, so the molds and quenched metals need to be annealed and tempered. The vacuum tempering furnace can quantify the surface of nonferrous metals and molds after high-temperature treatment, so that the nonferrous metals are not carburized and the surface is smooth and clean.
Main advantages of vacuum tempering furnace:
Safety and environmental protection;
Good production flexibility, can stop and open the furnace at any time;
The surface quality of the workpiece is good, and the processing deformation is small;
High degree of equipment automation;
Low equipment maintenance cost.
Process control of vacuum tempering furnace:
The vacuum annealing furnace can complete the tempering process under vacuum or inert gas protection.

The vacuum tempering series equipment takes the category "7.3 Horizontal double chamber high-pressure air-cooled type" as an example to list the main parameters of the current standard model equipment

Note:
The above are the parameters of our standard equipment. Shenyang Dongbo can carry out non-standard design and manufacturing according to the specific requirements of customers to meet their personalized needs. For example, the extreme vacuum degree can reach 10-4Pa or above, and the pressure rise rate can be better than 0.1Pa/h.
